Despite the fact that the wind tunnel tests have been carried out on iced transmission lines subjected to wind
load, it is not practical to do wind tunnel tests due to its high cost. This paper describes a detailed numerical simulation
method that can be used to instead of wind tunnel tests. Based on the galloping mechanism of iced transmission lines, the
aerodynamic test was simulated with the typical crescent super-large thickness iced four bundled conductors. One of the
results highlighted in this study is that the wind angle of attack had significant influence on the aerodynamics of iced conductors.
The Den-Hartog and O.Nigol coefficient were calculated to determine galloping of iced transmission lines, comparing
with the reference of wind tunnel test in the Zhejiang university, the range of the wind angle of attack to the bundled
conductor which can lead to gallop is larger than single wire, but the absolute value of amplitude is less than the single
conductor, split conductor is more likely to gallop than single conductor.
